Each pocket panel includes a pair offree edges major panel pocket 22 can be sized to receive the lower portions of eight and one-half inch by eleven inch sized papers, or can be sized to receive various other-sized papers or components therein. - The
major panels pocket panels spine 16 can be made of any of a wide variety of materials, including but not limited to cardboard, paperboard, plastic (such as polypropylene or vinyl), plastic encased cardboard, etc. Thepocket panels major panel - Each
free edge pocket panel major panel pocket 22. As best shown inFIGS. 2 and 3 , a stress relief feature, generally designated 38, may be located at the outer edge of eachfree edge 30, 32 (i.e. at or proximate to a location where afree edge secured edge stress relief feature 38 can be an opening, recess or cut-out (hereinafter collectively termed an opening 40) in thepocket panel opening 40 is generally zigzag or “z”-shaped having a pair of relativelyshort legs 42, 44 (aproximal leg 42 and a distal leg 44) connected by a longertransverse portion 46. - In the illustrated embodiment, each

Thetransverse portion 46 is positioned between thelegs distal leg 44 and the adjacentfree edge pocket 22. - An
opening 40 can be located at each position of eachpocket 22 where afree edge secured edge openings 40 help to reduce stress and tearing of thepocket 22 when thepocket panel major panel terminal tip 50 of theopening 40. In addition, the applied stresses are applied in the direction of the arrow A ofFIG. 3 . It can be seen that there is a relatively large amount of material of thepocket panel 20 about theterminal point 50 to help accommodate the stresses at theterminal point 50. In addition, because the stress A is directed generally perpendicular to the associatedfree edge 32, and generally parallel to the adjacentsecured edge 24, it can be seen that any tear in thepocket panel 20 can travel for a significant distance in the direction of arrow A before the tear would reach anyouter edges - Thus, it can be seen that the
proximal leg 42 of theopening 40 ofFIG. 3 guides any applied stresses inwardly away from thefree edge 32, thetransverse portion 46 guides the stresses further inwardly away from thefree edge 32 and away from theproximal leg 42. Finally, thedistal leg 44 guides the stresses even further away from thefree edge 32 and in a direction generally perpendicular to thefree edge 32. - The changes of directions, corners and
terminal point 50 of theopening 40 may be curved (i.e. having a radius of at least about 0.06 inches) to avoid the presence of sharp corners which can concentrate stresses. Theopening 40 may have a generally uniform width (i.e. between about 0.05 and about 0.2 inches) and may have a total length that is between about one and about ten times as long as its width. Theopening 40 may extend a total distance that is less than about 1/10 of the perimeter of thepocket 22. In one embodiment theproximal leg 42 of theopening 40 can terminate in a relatively wide mouth, as shown inFIG. 2 . - Thus, the
stress relief feature 38 allows thepocket panels major panel resistant pocket 22. Furthermore, thestress relief feature 38 can allow thepocket panels pocket 22. -
FIGS. 4 and 5 show anotherbinder 10 with a relativelylarge pocket panel 56 attached to the underlyingmajor panel 12 about threeedges short attachment lines 64, for example by welding. Thepocket panel 56 is unattached along itsfree edge 66. A pair of stress relief features 38/openings 40 having features similar to the stress relief features 38/openings 40 described above are provided at the outer tips of thefree edge 66 of thepocket panel 56. - In the embodiment of
FIGS. 6 and 7 , thepocket panel 56 is coupled to the underlyingmajor panel 12 about threesecured edges pocket panel 56 includes a freeupper edge 66. In addition, arivet 70 is located at each corner of thepocket panel 56, and extends through thepocket panel 56 andmajor panel 12 to securely couple thepocket panel 56 andmajor panel 12 together. Therivets 70 provide an extremely strong connection, but the location of therivets 70 also provides a position of high stresses when thepocket panel 56 is pulled away from themajor panel 12. Astress relief feature 38, in the form of an opening, recess or cut-out (hereinafter collectively termed an opening 72), can be positioned between eachrivet 70 and the adjacentfree edge 66. In the embodiment illustrated inFIGS. 6 and 7 , theopening 72 is a generally “v” or “u”-shaped notch. - When the
pocket panel 56 is pulled away from themajor panel 12, theopenings 72 allow thefree edge 66 to be pulled further away from theunderlying panel 12 before large stresses, which can cause tearing in thepocket panel 56, are induced in thepocket panel 56. Thus theopenings 72 provide a greater range of motion and direct stresses away from therivets 70. The tip of eachopening 72 may be curved, and may have a radius of at least, for example, about 0.05 inches, or at least about 0.1 inches, or at least about 0.5 inches, to help avoid or minimize tearing. - The pocket design of the present invention can be used in nearly any pocket used alone or in pockets used in conjunction with or integrated into other school or office items, such as binders, notebooks, portfolios, planners, date books, insert pockets and the like. Further it should be noted that the various materials and dimensions shown in the attached drawing are illustrative of only a few embodiments of the invention, and the invention is not limited to such materials and dimensions.
- Having described the invention in detail and by reference to the various embodiments, it should be understood that modifications and variations thereof are possible without departing from the scope of the invention.
- In one embodiment, the present invention is a pocket structure including first and second generally flat, planar panels.
